Stage-3 Audio Kit for 2024+ Harley-Davidson HD24-STG3
Stage-3 Audio Kit for 2024+ Harley-Davidson HD24-STG3
Performance Engineered: Each component of the Stage-3 kit is meticulously engineered for peak performance. The 6.5” and 6x9 speakers feature a heat-resistant motor structure and radiator ring that efficiently dissipate heat, ensuring consistent, powerful sound even under the most demanding conditions. Complementing the speakers, the 1000-watt digital amplifier delivers robust performance and is future-ready for expanding your system with additional speakers.
Plug and Play Design: Stage-3 delivers a complete plug-and-play solution in a single box, featuring direct-fit, model-specific 6.5” and 6x9” speakers, amplifier mounting plates, a saddlebag installation kit, and grilles. Engineered for seamless integration with the Skyline™ OS Harley-Davidson® infotainment system — it requires no radio flashing — making installation straightforward and hassle-free.
Precision-Tuned: Featuring long-throw woofers for high output and deep, extended low-end response, these speakers deliver powerful yet balanced sound. The large voice coil and extended frequency range enhance bass output, ensuring louder, more dynamic, and long-lasting performance.
Total Control: With the RF Connect app, tuning your system is as easy as tapping your screen. Connect to the amplifier via Bluetooth® to instantly load a DSP tune matched to your exact Rockford Fosgate® motorcycle audio kit. You can also fine-tune your ride by adjusting gain and crossover settings digitally, customizing your sound, your way, all from your smartphone.
Element Ready™: Purpose-built for the harsh motorcycle environment, this kit includes watertight, grommeted installation harnesses with OEM-style and Deutsch™ DT connectors. Designed to withstand water, dirt, UV exposure, and constant vibration, it ensures long-lasting, reliable audio performance.

HD24-STG2 & STG3 | Installation

True Plug-and-Play
True plug-and-play with pre-terminated harnesses and OEM-grade terminals for seamless factory integration.
Rockford Sonic Signature
Get maximum performance from your Rockford Fosgate Stage Kit by loading our signature DSP tunes through the RF Connect app. Developed by our engineers using a 6-microphone array, these DSP presets feature precision crossover, gain, and limiter settings, optimized for open-air audio performance. With over 45 years of tuning expertise at your fingertips, DSP presets take the guesswork out of tuning your audio system, allowing you to instantly achieve high-performance output with confidence.
Active Recovery™
Reduces the amplifier’s idle current and thermal load when volume is muted or reduced to zero, allowing it to enter an active recovery state and rebuild its thermal capacity for peak performance. Once the volume increases, the amplifier instantly turns back on, allowing the amplifier to play for longer durations.
Neodymium Motors
Neodymium is up to 35% lighter and 65% smaller over traditional ferrite and ceramic, while having the same motor strength (Bl). This allows the speaker to fit factory locations without any modification.
Coherent-Phase Alignment
Precisely recessing the tweeter inside the woofer voice coil geometry ensures phase-aligned sound waves from both drivers arrive at the listener’s ears simultaneously. This coherent-phase response minimizes destructive interference and phase cancellation, resulting in significantly improved stereo imaging, spatial accuracy, and vocal clarity.
Performance Engineered
Rooted in a legacy of American innovation, our products are proudly designed and developed in Tempe, Arizona, reflecting decades of expertise.
